Specification of Letters Patent.

ILLINOIS.

Application filed May 6, 1918. Serial No. 232,820,

To all whom it mag concern 7 Be it known that I, \VILLIAM J. H. STRONG, a citizen of the United States, and a resident of Chicago, county of Cook, and Sta-teof Illinois, have invented a certain new, useful, and Improved Heat Motor, of whichthe following isa full, clear, concise, and exact description, reference-being had to accompanying drawings, forming a part of this specification. v

My invention relates to improvements in heat motors and hasspecial reference to improvements in a portable combined hot air motor andfanr Among the severalobjects of my invention are to provide a light strong open-work motor supporting structure or base which can readily be secured to the body of the motor and as easily separated therefrom'for shipping purposes, which base shall comprise three independent flat leg members adapted to be separately secured to the motor and when removed from the motor adapted to be packed within a minimum space for shipment.

A further object of my invention is to provide a hot air motor with very simple means for removably holding andsupporting a font for liquid fuel, in place, and from which the font can be easily and quickly released. v

My invention resides in adapted to use'a liquid fuel, having avertical working cylinder, a light open work or skeleton base, attached at its upper end to the cylinder and supporting the. cylinder at'a suitable height, the base provided with yielding arms adapted to engage andhold a fuel font below the cylinder, the arms being capable of being drawn outward against their resiliency to release the font.

My invention also consists in, a hot air motor of the class described, and having a light, skeletonba'se, comprising three vertically arranged leg members made of strap metal, and'each' yielding arm formed for engagement with the periphery of a fuel font, and at least one of the arms provided with a hooked finger piece whereby the arm may bereadily withdrawn to permit the removal or placement of the fuel font. p My invention also consists in the several arrangements and combinations of parts and in the featuresof construction, whereby I am enabled to attain the" above described,

a hot air motor' pending therefrom,

leg carrying a dependingand other objects, and all as hereinafter described, and particularly pointed out in the appended claims.

My invention will be more readily understood by reference to the accompanying drawings forming a part of this specification and in which:

Figure 1 is a fragmentary side elevation of a combined hot air motor and fan illustrating one embodiment of my invention;

Figure2 is a horizontal plan view of the base taken on the line 2-2 of Figure 1; and

Figure 3 is a vertical sectional view of the lower part of the motor and the base taken on the line 3-3 of Figure 2; A'spec'ial object of my invention is to provide a low base especially adapted for use with the hot air motor and fan disclosed in my copending, application for Letters Patent of the United States entitled Hot air motor, Serial No. 17 0,115, filed Ma 21st, 1917.

The form'of motor and base disclosed in said application is particularly arranged for use with a kerosene lamp as the source of heat, as well as otherforms of fuel, andfor' saidspecial purpose requires a considerable Patented June 27, 1922.

space below the motor forthejreception of thelamp. V The present invention relates more partic: ularly to of very simple construction. i

a generator cylinder 3 dea shaft housing 4 above the cylinder and a spacing member or cylin} der 4' supporting the shaft housing upon the cylinder 2. While the motor may be used for different power purposes, I have illustrated the otor as provided with a ventilating fan 5,, mounted upon the shaft of'the motor", 1 1 ,f"

The generator cylinder 3 is secured at'its upper end to the lower end of the working 'ing cylinder 2,

cylinder and depends therefrom. 1 Below the lower. end 6 of the generating or hot" air cylinder provide a fuel font 7 which is low and of relatively largewdiameter, and is provided with'a centrally arranged burner 8" adapted to' impinge its flame upon the lower end 6 of the generating cylinder. Y'For supporting the font"? close to the floor, and the motor a the P p height the use. of alcohol orgasoline as a fuel, which permits the use of a low base.

generally a pending application, provided with a workabove the font, I provide three similar legs 9, equi-spaced around the motor and each comprising a unitary structure independently secured to the cylinder 2 and each adapted to assist in providing a relatively low base. These legs are made of strap or strip metal and each consists of a main leg member 9 consisting of a vertical part 10 and an outwardly inclined section 11 terminating in a durved foot part 12. The securing or attaching section 10 is bent inwardly at its upper end providing an attaching lug 13 provided with a flat upper surface adapted to contact with the lower surface of an annular supporting flange 14 provided on the cylinder 2 adjacent to. its lower end. Each member 9 is securely attached to the motor at its upper end by a screw 15, a hole being provided in the flange 15 therefor.

Surrounding the lower end of the generator cylinder 3 is a guard cylinder 16 which depends below the lower end of the cylinder 3 and has a contracted lower end with a central opening 17 for the insertion of the burner 8. This guard cylinder 16 is of a diameter to be received between the several vertical portions 10 of the several legs and each leg is secured to the cylinder by a screw 18. The cylinder 16 thus serves the double purpose of its function relating to the motorof a guard cylinder and the added function of forming a part of the base to assist in holding the three leg members rigidly together. The outwardly inclined lower end 11 of the leg members 9 provide a central space between the legs for the re ception of thefuel font 7.

To brace theleg members 91 provide a brace member 18 for each leg, having its upper end 19. riveted or otherwise securely fastened to the vertical part 10 of the leg inember 9 adjacent to its upper end,.and

having its lower end 20 secured by a rivet or otherwise tothe outwardly inclined part 11 of the mainleg member .9. The brace member 18 thus-serves to make the leg a rigid'base supporting member and the three legs in combination with the guard cylinder 16 form a rigid base adaptedto support the motor in a stable condition.

' To support the font '7 in proper central position -.in the space between the several legs and centrally beneath the generator a cylinder, 3, I provide on each leg a dependingffont engaging arm or member 21 secured at its upper end to the main. leg member adjacent to the upper end of the inclined vportion 11, and providediat its lower end with an inwardly .formed shoulder -22 adapted to project [beneath the edge of the font 7 and support thesame. The :arm 21 is a spring armszand I form it to .normallyjstand in the mn'erQdotted position when :the font is not place.

The font is of peculiar contour at its periphery, having a relatively deep conical upper part 23 and a sharper lower conical outer edge 24-. The upper part 23 of the periphery is adapted to spread the spring supporting members when the motor is lifted and placed down upon the font, the font thus entering between the several supporting members21 and spreading them apart until the shoulders 22 pass the larger periphery 23 of the font. Whenthis point is reached the resiliency'of the several arms causes them to enter beneath the font and automatically raise it to its proper position as shown in full lines. To release the font from its supported position, one or more of the arms 21 are drawn or forced outwardly to permit the font to pass the shoulder 22, and for conveniently forcing the arms .out for this purpose, each of which is provided with a finger hook piece 26 at its lowerend in convenient position to be grasped by the hand when grasping the leg and be pulled outwardly to the dotted position. When one or more of the supports. 21 are thus drawn out, the font can be freely removed from its operative position, or a font can be readily entered into operative position.

As shown and described, the leg members 8 are independentrof each other and are each independently secured to the motor by means of the flange let and screws 15 and are rigidly secured together by means of the guard 16 and screws 18. They are relatively thin or Hat and whenremovedfrom. the motor can be stacked or arranged compactly together to occupy a minimum space for shipment. The importance of this feature will be recognized when it is understood that most of the motors of this formmanufactured, are shipped to foreign countries, 'and itis necessary in this trade to reduce the shipping space required for .each motorto a minimum.

As many modifications of myinvention in the art, .I do not limit or confine .myinvention to the specific structures herein shown and described except as defined by the appended claims.

I claim: 7
